Abstract: This application discloses a data access method applied to a first storage node in a storage system. The first storage node communicates with at least one second storage node. A physical disk included in the at least one second storage node is mapped as a virtual disk of the first storage node. The method may include: receiving a first write request, where the first write request carries first to-be-written data; striping the first to-be-written data to obtain striped data, and writing the striped data to a physical disk and/or the virtual disk of the first storage node; and recording a write location of the striped data. For example, the technical solution may be applied a storage system that includes an NVMe SSD.

Abstract: A data processing system and method, and a corresponding apparatus, where the data processing system includes a controller and at least two storage nodes. The controller is configured to receive, using a first coupling between the controller and a host, an operation request received from the host, where the operation request includes an identity of target data and an operation type, determine at least one target storage node from the at least two storage nodes according to the identity of the target data, and send an instruction message to the at least one target storage node using a second coupling to the at least one target storage node, where the at least one target storage node is configured to send the target data to the host or obtain the target data from the host according to the instruction message.
